- internal/ports/portsfake: hand-written in-memory fakes for all 9 ports
(Users/Libraries/Books/Progress/Bookmarks/RateLimiter/Scanner/Media/Uploads);
error semantics mirror the real store exactly — pgx.ErrNoRows for misses,
store.ErrLastAdmin guard, and *pgconn.PgError{Code:23505} for unique
violations (ports.IsUniqueViolation only accepts the PgError shape, so the
fakes must produce it to exercise the 409 branch without touching prod code)
- Media/Uploads fakes are hook-programmable: one field per error branch, so a
test can force e.g. CompleteErr=ErrIncomplete without stubbing the rest
- Scanner fake is mutex-guarded + WaitForScan: handler fires ScanLibraryByID
in a goroutine, tests stay deterministic
- router_test.go: TestRouterContract pins all 27 routes — any route table
change now fails the test explicitly
- handler unit tests (~30 cases, no PG/Redis): users CRUD branches (self-delete
400, last-admin 400, dup 409, 204 ok), library reserved names (contract:
code=bad_request message=reserved_name, per original impl), upload sentinel
mapping (413/400/404 per branch)
- NewRouter takes pure port interfaces; main.go distributes *store.Store
across the 5 store ports at the composition root
Full gate green: gofmt, vet, go test -p 1 (real PG+Redis, 0 skip)
